Kocher | March 7, 2000 |
A laminate includes: a. a first, substantially gas-impermeable film; b. a second, delaminatable film; and c. a third, gas-permeable film. The second film is positioned between the first and third films and the laminate is capable of delaminating within the second film when the laminate is subjected to a delaminating force. A portion of the delaminatable film thus remains bonded to the gas-permeable film after delamination.
